v4l2codecs is the gstreamer plugin for V4L2 stateless video hardware
decoding. The Rockchip SoCs that have a VPU all seems to be based on
Hantro, RKVDEC or RKVDECv2, all stateless encoding/decoding VPUs.

Therefore, let's enable VPU decoding in Gstreamer whenever possible,
when the SoC supports it.

PX30, RK3066, RK3188, RK3288, RK3328, RK3399, RK356x and RK3588(s) all
have at least one Hantro VPU.

RK3328, RK3399, RK356x and RK3588(s) all have at least one
RKVDEC/RKVDECv2 VPU (though not necessarily supported in the upstream
kernel just yet).

=== PX30
Tested on PX30 Ringneck with with Haikou+Haikou Video Demo adapter:

$ gst-launch-1.0 filesrc location=$FILE ! parsebin ! v4l2slh264dec ! waylandsink

with FILE storing the path to any h264 file, e.g.
https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_h264.mov
https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_h264.mov

Needed packages are:
- weston
- gstreamer1.0-plugins-bad (for waylandsink and v4l2slh264dec)
- gstreamer1.0-plugins-base (for parsebin)

A few frames are dropped every other second for 1080p but otherwise
smooth.

=== RK3399
Tested on RK3399 Puma with Haikou:

$ gst-launch-1.0 filesrc location=$FILE ! parsebin ! v4l2slh264dec ! waylandsink

with FILE storing the path to any h264 file, e.g.
https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_h264.mov
https://download.blender.org/demo/movies/BBB/bbb_sunflower_2160p_30fps_normal.mp4.zip

Needed packages are:
- weston
- gstreamer1.0-plugins-bad (for waylandsink and v4l2codecs)
- gstreamer1.0-plugins-base (for parsebin)

=== RK3588

Tested on a RK3588 Tiger with Haikou+Haikou Video Demo adapter - on a
downstream v6.6 (upstream-based, not Rockchip BSP-based) with DSI
patches - :

$ gst-launch-1.0 filesrc location=$FILE ! parsebin ! v4l2slav1dec ! fakesink

with FILE storing the path to any AV1 file, e.g.
http://download.opencontent.netflix.com.s3.amazonaws.com/AV1/cmaf/spark-8b-59.94fps/spark_606kbps_432p.mp4
https://woolyss.com/f/av1-nosound-chimera.mp4
https://woolyss.com/f/av1-opus-sita.webm

Needed packages are:
- gstreamer1.0-plugins-bad (for fakesink and v4l2slav1dec)
- gstreamer1.0-plugins-base (for parsebin)

For some reason though, waylandsink is very choppy. Combining
fpsdisplaysink with fakesink shows a ~60fps when decoding the 432p file,
~24fps for the two others.
Note that 10b-depth isn't supported (at least in my setup).

(Most) Rockchip SoCs have a VPU that can be used with v4l2codecs plugin
from gstreamer. In the kernel this VPU is supported by the Hantro,
RKVDEC or RKVDECv2 drivers which do both stateless HW video encoding and
decoding, however gstreamer only supports decoding for now, see [1] for
encoding support.

All Rockchip SoCs supported in this layer to the exception of the RK3308
have at least one stateless VPU according to the compatible list in the
Linux kernel, so all SoC includes (except the one for the RK3308) now
set ENABLE_STATELESS_VPU_GST value to enable VPU decoding via gstreamer.

Note that RK3588 upstream Linux kernel only supports AV1 decoding right
now. Also, there's currently no video output support, so this was tested
on a private downstream branch supporting DSI on RK3588 Tiger with
Haikou + Haikou Video Demo adapter).

Note that Gstreamer v4l2codecs only added support for av1 decoding in
1.23.1, so the RK3588 part of this series doesn't necessarily make sense
to be backported right now to other branches (e.g. scarthgap or
kirkstone), at the very least until more than AV1 decoding is supported
(which will probably land this year or the next).

Changes in v2:
- rename HAS_HANTRO to ENABLE_STATELESS_VPU_GST
- add documentation in README
- squash all commits
- mention rkvdec/rkvdecv2 as well
- Link to v1: https://lore.kernel.org/r/20240820-gst-hantro-v1-0-335c4eaf8e8b@cherry.de
